WATER-TRAP.

SPECIFICATION forming part of Letters Patent No. 293,438, dated February12, 1884.

Application filed May 9, 1883. (No model.) Patented in Canada November11, 1882, Nos. 15,777, 16.673, and 16,674.

To aZZ whom it may concern.-

Be it known that 1, WILLIAM J. ENGLISH, a citizen of the United States,residing at Gohoes, in the county of Albany and State of New York, havein vented new-and useful Im provements in Water-Traps, of which thefollowing is a specification.

This invention relates to awater-trap of that class which I havedescribed in Letters Patent No. 249,031, granted to me November 1, 1881.I

My present invention consists in a watertrap composed of threesubstantially parallel limbs communicating through two bends, alatcrally-proj ecting enlargement formed in the connecting-limb, and avent-opening formed on a rectilinear upward continuation of thedischarge-limb. My trap is cast of lead, and provided with bell-shapedsockets for the purpose of making the connections with theinletpipe andwith the waste-pipe.

In the accompanying drawings, Figure 1 represents an elevation, partlyin section. Fig. 2 is a vertical section in the plane as :r, Fig. 1.Similar'letters indicate correspond ing'parts. In the drawings, theletter A designates my trap, which is composed of three limbsviz.,

' the inletlimb a, the connecting-limb b, and

the discharge-limb c. The connecting-limb b is substantially parallelwith the limbs or and c, and itcommunicates with the limb a by a bent,d, and with the limb c by a bent, e. The connecting-limb b is providedwith an enlargement or chamber, 71, (see Fig. 2,) the object of which isto retain a quantity of air and to prevent the trap from being siphonedout. This chamber also serves as a reservoir containing a large quantityof water, which is not so quickly evaporated as the smaller quantitycontained in a limb of ordinary section. The mouth f of the inlet-limb aconnects by apipe,

m, with the sink or other device on which thetrap is to be used. Thedischarge-limb 0 extends upward and forms a vent, i, for gases, beingconnected with a pipe, Z, for discharge in any suitable place. By havingthe vent t chocked up with grease. My vent is cast solid with the trap,which is a great saving in labor.

My trap is cast of lead, in two sections, A A the section A beingprovided with abell,

n, to receive the end of the section A the M connection being made bysolder or other suit able means. By referring to the drawings it will beseen that the two sections A A are united in the middle of the chamberh, and that the mouth f of the inlet-limb a, as well as the vent-opening1; of the discharge-limb c, are made in the form of bells, thebell-shaped mouth f being intended to receive the pipe m, which leads tothe sewer or other device, as already stated, while the bell-shapedventopening z is intended to receive the pipe Z, for the discharge ofgases.

I am aware that it is not new to construct a water-trap of two parallellimbs connected by an intermediate limb. with a vent in the intermediatelimb, and therefore lay no claim thereto.

What I claim as new, and desire to secure by Letters Patent, is-

1.7 A water-trap composed of three substantially parallel limbs, a b c,communicating through two bents, d e, an enlargement formed in theconnecting-limb Z), and a vent formed by extending the walls of thedischarge-limb above the connection with bent e, wherebythe vent islocated above the dischargelimb and not in the bent e, substantially asdescribed.

2. A watentrap composed of two sections, A A the section A forming theinlet-limb a and part of the connecting-limb b, and being provided atits ends with bells f a, while the section A forms the discharge limbs cand part of the connecting-limb b, and is provided with a hell, i,substantially as shown and described.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witnesses.
